Anti-Müllerian Hormone (AMH) is a glycoprotein dimer that belongs to the transforming growth factor-beta (TGF-β) family. It is produced by the granulosa cells of ovarian follicles.

AMH levels in the blood are used to assess a woman's ovarian reserve, which is the number of viable eggs remaining in the ovaries. This is particularly useful for evaluating fertility potential and predicting the onset of menopause.

The normal reference range for AMH is typically between 1–10 ng/mL. Levels below this range may indicate diminished ovarian reserve, while higher levels can be associated with conditions like polycystic ovary syndrome (PCOS).

AMH testing is often used in conjunction with other fertility assessments to provide a comprehensive picture of a woman's reproductive health. It is also used to monitor ovarian response in fertility treatments.
